Hindko (ہندکو pronounced [/Hindkoŭ/], also Hindku, Hinko, or Western Lahnda,) is a dialect of Northern Punjabi, spoken by Hindkowans in Pakistan. The literal meaning of the word "Hindko" is "Mountains of the Indus". The word "Hind" is the Persianised reference to the regions associated with the Indus River immediately to the east of Persia and "Ko" means mountains. The word Hindko has also been interpreted to mean the language of Ancient India. The term is also found in Greek references to the mountainous region in eastern Afghanistan and northern Pakistan as Καύκασος Ινδικός (Caucasus Indicus). The language is spoken in areas of Khyber Pakhtunkhwa (including Hazara), Punjab (including Attock), and Azad Kashmir by an estimated 2.2 to 4 million.

There is no proper, formal generic name for these people because they belong to diverse ethnicities and tend to identify themselves by the larger families, castes and tribes. However the people of the largest group in the districts of Haripur, Abbottabad and Mansehra are sometimes recognised collectively as Hazarawal, named after the Hazara Division that comprises these districts. In Peshawar city they are referred to as "Kharay" meaning City-dwellers or Hindkowans.
